In an era of turmoil in the court and chaos in the world, Song Xiaoliu, a small figure in the world, wanted to sell tofu in a stable manner, but an unexpected incident led to him being involved in a struggle within the court. Along with Liu Hanxiang and Wang Datou, they successively resolved major crises such as the imperial court's seizure of power, clan conspiracy, and the rise of dark forces. They accidentally met Du Qianxue, who was living among the people, and formed a small group. From then on, they "used humor as a weapon" in troubled times, turned enemies into friends, and survived against the odds. After going through machinations, pursuits, and wars, they smiled at life and finally broke through, discovering that real growth lies in inner humor and precious friendship. The whole book is full of humor and fast pace, with ups and downs, but the plot is always compact and lively. The three volumes respectively describe three great changes in the turbulent times. Each volume is self-contained and interrelated.
